Heart valve prostheses including torque anchoring mechanisms and delivery devices for the heart valve prostheses

Abstract

A delivery device for delivery and deployment of a heart valve prosthesis with a torque anchoring mechanism includes a balloon having a shaped surface configured to engage a corresponding shaped surface of the heart valve prosthesis. The balloon is configured to rotate about a central longitudinal axis of the delivery device to rotate the heart valve prosthesis.

1 - 17 . (canceled) 
     
     
         18 . A heart valve prosthesis comprising:
 a frame, wherein the frame is radially compressible and radially expandable, the frame comprising:
 including an inflow rim; and 
 an outflow portion, wherein the inflow rim flares radially outward from the outflow portion; and 
   a prosthetic heart valve coupled to an inner surface of the outflow portion of the frame,   wherein the inflow rim is rotatable relative to the outflow portion of the frame.   
     
     
         19 . The heart valve prosthesis of  18 , further comprising barbs extending from the inflow rim, wherein the barbs are configured to engage tissue by rotation of the inflow rim relative to the outflow portion in situ. 
     
     
         20 . The heart valve prosthesis of  claim 19 , wherein the barbs extend from a downstream surface of the inflow rim. 
     
     
         21 . The heart valve prosthesis of  claim 19 , wherein the barbs extend circumferentially such that rotation thereof causes the barbs to engage tissue. 
     
     
         22 . The heart valve prosthesis of claim  17 , wherein the inflow rim is rotatably coupled to the outflow portion at a joint. 
     
     
         23 . The heart valve prosthesis of  claim 22 , wherein the joint is a flexible material. 
     
     
         24 . The heart valve prosthesis of  claim 23 , wherein the flexible material is a fabric material. 
     
     
         25 . The heart valve prosthesis of  claim 22 , wherein the joint is configured to enable rotation between the inflow rim and the outflow portion, but not longitudinal separation of the inflow rim and the outflow portion. 
     
     
         26 . The heart valve prosthesis of  claim 22 , wherein the joint comprises a groove in one of the inflow rim or the outflow portion and a lip the other of the inflow rim or the outflow portion, wherein the lip is disposed in the groove to enable rotation and restrain longitudinal movement of the inflow rim and the outflow portion relative to each other. 
     
     
         27 . The heart valve prosthesis of  claim 22 , wherein the joint comprises a tubular portion of the inflow rim extending towards outflow portion, a lip of the tubular portion, and a groove disposed at an inflow end of the outflow portion, wherein the lip is disposed in the groove to enable relative rotation between the inflow rim and the outflow portion. 
     
     
         28 . The heart valve prosthesis of  claim 27 , wherein the lip extends radially inward from the tubular portion of the inflow rim. 
     
     
         29 . The heart valve prosthesis of claim  17 , further comprising a plurality of arms coupled to the outflow portion of the frame. 
     
     
         30 . The heart valve prosthesis of  claim 29 , wherein the plurality of arms are coupled to an outflow end of the outflow portion. 
     
     
         31 . The heart valve prosthesis of  claim 30 , wherein the plurality of arms are configured to capture native leaflets of a native heart valve between the plurality of arms and the outflow portion of the frame. 
     
     
         32 . The heart valve prosthesis of  claim 30 , wherein the arms extend longitudinally away from the outflow end of outflow portion with the frame in a radially compressed configuration, and are configured to fold back to extend towards the inflow rim in a radially expanded configuration of the frame.
